Climbing rose plant named ‘Sprofifth’

ABSTRACT

A new and distinct variety of climbing rose plant, herein referred to by its cultivar name, ‘Sprofifth’, is provided which forms abundantly on a substantially continuous basis attractive, cup-like shaped red colored blossoms with dark red stripes. Attractive glossy, dark green foliage is formed, which contrasts beautifully with the blossoms. The growth habit is very bushy and climbing. The new variety is well suited for providing attractive ornamentation in the landscape.

Botanical/commercial classification: Latin name—Rosa hybrida.

Varietal denomination—‘Sprofifth’.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida climbing rose plant was created during April of 2010 in Bakersfield, Calif., U.S.A., by artificial pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., the seed parent) was the ‘WEKroalt’ variety (U.S. Plant Pat. No. 11,518). The male parent (i.e., the pollen parent) was the ‘Sprothrive’ variety (U.S. Plant Pat. No. 23,549).

The parentage of the new variety can be summarized as follows: ‘WEKroalt’ x ‘Sprothrive’

The seeds resulting from the above pollination were sown and small plants were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a single plant of the new variety.

It was found that the new variety of rose plant of the present invention possesses the following combination of characteristics:

-   -   (a) forms attractive, cup-like shaped, red colored blossoms with         dark red stripes,     -   (b) displays a very bushy and climbing growth habit,     -   (c) forms vigorous vegetation, and     -   (d) provides attractive ornamental glossy, dark green foliage.

The new variety well meets the needs of the horticultural industry. It can be grown to advantage as ornamentation in parks, gardens, public areas, and in residential settings. Accordingly, the plant is particularly well suited for growing in the landscape.

The new variety of the present invention can readily be distinguished from its ancestors. More specifically, the ‘WEKroalt’ variety (i.e., the seed parent) grows shorter and displays larger blossom compared to the new variety. In addition, the ‘Sprothrive’ variety (i.e., the pollen parent) provides solid dark bright red colored flowers and a round and bushy growth habit, whereas the new variety displays striped red colored flowers and a climbing growth habit. Moreover, the new variety can be readily distinguished from other similar non-parental varieties. For example, the ‘Radwin’ variety (U.S. Plant Pat. No. 19,310) displays solid red colored blossoms, whereas the new variety displays striped red colored flowers.

The new variety has been found to undergo asexual propagation at Wasco, Calif. and at Cochranville, Pa. by a number of routes, including vegetative cuttings. Asexual propagation by vegetative cuttings at Wasco, Calif. and at Cochranville, Pa. has shown that the characteristics of the new variety are stable and are strictly transmissible by such asexual propagation from one generation to another. Accordingly, the new variety undergoes asexual propagation in a true-to-type manner.

The new variety has been named ‘Sprofifth’.

The new variety was first offered for sale on March, 2019 by the inventor or another who obtained the new variety directly or indirectly from the inventor and the first sale was on Apr. 30, 2019 by the inventor or another who obtained the new variety directly or indirectly from the inventor.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph of FIG. 1 shows as nearly true as it is reasonably possible to make the same, in a color illustration of this character, a typical specimen of the new variety. The rose plant of the new variety was approximately three years of age and was observed during May 2019 while growing on its own roots and growing outdoors in a three-gallon container at Cochranville, Pa., U.S.A.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart, 2015 edition), London, England. The terminology which precedes reference to the chart has been added to indicate the corresponding color in more common terms. The description is based on the observation of three-year-old specimens of the new variety during May while growing on their own roots in a three-gallon container at Cochranville, Pa., U.S.A.
